| CVE-2015-8340 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| The memory_exchange function in common/memory.c in Xen 3.2.x through 4.6.x does not properly release locks, which might allow guest OS administrators to cause a denial of service (deadlock or host crash) via unspecified vectors, related to XENMEM_exchange error handling. | ||||
| CVE-2015-8555 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-12 | N/A |
| Xen 4.6.x, 4.5.x, 4.4.x, 4.3.x, and earlier do not initialize x86 FPU stack and XMM registers when XSAVE/XRSTOR are not used to manage guest extended register state, which allows local guest domains to obtain sensitive information from other domains via unspecified vectors. | ||||

NOTE: this vulnerability exists because of an incorrect fix for CVE-2013-2076. | ||||
| CVE-2016-3960 | 3 Fedoraproject, Oracle, Xen | 3 Fedora, Vm Server, Xen | 2025-04-12 | N/A |
| Integer overflow in the x86 shadow pagetable code in Xen allows local guest OS users to cause a denial of service (host crash) or possibly gain privileges by shadowing a superpage mapping. | ||||
| CVE-2016-3961 | 2 Canonical, Xen | 2 Ubuntu Linux, Xen | 2025-04-12 | N/A |
| Xen and the Linux kernel through 4.5.x do not properly suppress hugetlbfs support in x86 PV guests, which allows local PV guest OS users to cause a denial of service (guest OS crash) by attempting to access a hugetlbfs mapped area. | ||||
| CVE-2015-7971 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| Xen 3.2.x through 4.6.x does not limit the number of printk console messages when logging certain pmu and profiling hypercalls, which allows local guests to cause a denial of service via a sequence of crafted (1) HYPERCALL_xenoprof_op hypercalls, which are not properly handled in the do_xenoprof_op function in common/xenoprof.c, or (2) HYPERVISOR_xenpmu_op hypercalls, which are not properly handled in the do_xenpmu_op function in arch/x86/cpu/vpmu.c. | ||||
| CVE-2015-8615 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| The hvm_set_callback_via function in arch/x86/hvm/irq.c in Xen 4.6 does not limit the number of printk console messages when logging the new callback method, which allows local HVM guest OS users to cause a denial of service via a large number of changes to the callback method (HVM_PARAM_CALLBACK_IRQ). | ||||
| CVE-2015-7835 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| The mod_l2_entry function in arch/x86/mm.c in Xen 3.4 through 4.6.x does not properly validate level 2 page table entries, which allows local PV guest administrators to gain privileges via a crafted superpage mapping. | ||||
| CVE-2015-7812 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| The hypercall_create_continuation function in arch/arm/domain.c in Xen 4.4.x through 4.6.x allows local guest users to cause a denial of service (host crash) via a preemptible hypercall to the multicall interface. | ||||
| CVE-2015-5307 | 6 Canonical, Debian, Linux and 3 more | 9 Ubuntu Linux, Debian Linux, Linux Kernel and 6 more | 2025-04-12 | N/A |
| The KVM subsystem in the Linux kernel through 4.2.6, and Xen 4.3.x through 4.6.x, allows guest OS users to cause a denial of service (host OS panic or hang) by triggering many #AC (aka Alignment Check) exceptions, related to svm.c and vmx.c. | ||||
| CVE-2015-7311 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| libxl in Xen 4.1.x through 4.6.x does not properly handle the readonly flag on disks when using the qemu-xen device model, which allows local guest users to write to a read-only disk image. | ||||
| CVE-2015-6654 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| The xenmem_add_to_physmap_one function in arch/arm/mm.c in Xen 4.5.x, 4.4.x, and earlier does not limit the number of printk console messages when reporting a failure to retrieve a reference on a foreign page, which allows remote domains to cause a denial of service by leveraging permissions to map the memory of a foreign guest. | ||||
| CVE-2015-4164 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| The compat_iret function in Xen 3.1 through 4.5 iterates the wrong way through a loop, which allows local 32-bit PV guest administrators to cause a denial of service (large loop and system hang) via a hypercall_iret call with EFLAGS.VM set. | ||||
| CVE-2015-3259 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| Stack-based buffer overflow in the xl command line utility in Xen 4.1.x through 4.5.x allows local guest administrators to gain privileges via a long configuration argument. | ||||

| Xen 4.3.x, 4.4.x, and 4.5.x, when using toolstack disaggregation, allows remote domains with partial management control to cause a denial of service (host lock) via unspecified domctl operations. | ||||
| CVE-2015-2752 | 2 Fedoraproject, Xen | 2 Fedora, Xen | 2025-04-12 | N/A |
| The XEN_DOMCTL_memory_mapping hypercall in Xen 3.2.x through 4.5.x, when using a PCI passthrough device, is not preemptible, which allows local x86 HVM domain users to cause a denial of service (host CPU consumption) via a crafted request to the device model (qemu-dm). | ||||
| CVE-2015-2152 | 2 Fedoraproject, Xen | 2 Fedora, Xen | 2025-04-12 | N/A |
| Xen 4.5.x and earlier enables certain default backends when emulating a VGA device for an x86 HVM guest qemu even when the configuration disables them, which allows local guest users to obtain access to the VGA console by (1) setting the DISPLAY environment variable, when compiled with SDL support, or connecting to the VNC server on (2) ::1 or (3) 127.0.0.1, when not compiled with SDL support. | ||||
| CVE-2015-2044 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
